SPECIFICATION forming part of Letters Patent No. 396,204, dated anuary 15, 1889.

Application filed July 26, 1888. Serial No. 281,153. (No model.)

T 0 all whom it may concern:

Be it known that I, ANDERS HAGQVIST, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Flows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of. reference marked thereon, which form part of this specification, in Which Figure 1 is a side View of my improved plow, the share being turned to the side of the landside opposite to that shown. Fig.- 2 is a vertical sectional view through Fig. 1 in the plane of the beam, shoe, and landside. Fig. 3 is a sectional view similar to Fig. 2, but showing the position of the parts when the lever is retracted and the mold-board is partly turned over the shoe. Fig. 4 is a plan view showing the share and handles in different positionsby the aid of dotted lines. Fig. 5 is a rear view, the handles being removed. The

' remaining figures are detail views of various portions of the plow.

This invention is an improvement in what are generally known as hillside-plows, and its objects are to provide a simple and efficient mechanism for shifting the mold-board to the right or left of the landside or beam without the necessity of lifting the plow-shoe, so that the furrow can be cut either right or left hand,

7 as the plowman wishes; to provide means for backing and elevating the plow-beam without moving the landside or handles, so that the beam will be out of the way of the mold-board when the latter is shifting; to make the shifting of the beam and mold-board simultaneous; to adjustably attach the handles to the shoe of the plow or landside, so that they can be shifted to suit the position of the moldboard and locked in such position; to provide improved attachments of the shifting moldboard to the landside or shoe, whereby the mold-board will be properly braced to sustain the thrust and pressure of the earth thereagainst, and, finally, to so connect the operat- 7 ing mechanismsof the mold-board, beam, and

' a locking device for the handles that they can all be actuated by the movement of a single lever conveniently placed for operation by the plowman'. These objects are attained in my present invention, which may be readily understood from the following description.

Reference being had to the accompanying drawings by letter, A des'ignates'the shoe of the plow, upon the bottom of which is secured or formed-the landside a,'which is preferably vertically at rear, and in its upper front face is formed an inclined socket, B, and this socket communicates with a similarly-incl'ined channel, b, which in reality forms but a continuation of the socket at the top and rear of the shoe. The side walls of channels 17 are extended rearward beyond the shoe, forming opposite downwardly-inclined arms or lugs C O, for a purpose hereinafter referred to.

Dis the plow-beam, which is of ordinary hook form, its short lower arm or foot, d, being dressed to fit nicely in socket B and channel I), which are angular in'cross-secti'on, preferably, to prevent rocking of thebeam on the shoe. When the foot d isseated in the socket, the beam is in proper working position, and forward draft thereon only binds it more securely in the socket and draws the shoe with it. The beam is vertically slotted at its bend, as shown at E, said slot extending into foot cl, and in said slot, near the lower end thereof, is pivotally secured on a bolt, e, the front end of a link,F, the other end of which is pivotally connected to the end of an arm, f, mounted on a short sliaft, G, journaled between the arms C G of the shoe, as shown,

and which arm f can be rocked by 'an upstanding lever, g, so that the plow-beam is longitudinally movable and can be drawn backward on the shoe, partly disengaging it from socket B, as is evident. In order to prevent the beam being drawn too far rear-' ward, and also to prevent toomuch strain being put on the mouth of socket B and end of foot d when the beam isretracted should theteam attached to the beam start, I may employ a transverse key piece or boss, -H, secured to or formed on the lower edge of beam D in front of pin e, the ends of which key work ininclined slots h 71, formed in the side walls of channel Z), as shown.

The mold-boa1d I is doulfle-faced, and is formed with two similarbut oppositely-curved wings, i 1', audits share or point .l is made triangular, as shown, its side edges, j, being sluirpened and so bent that if theshm-e be turned to either right or left side of the shoe one of the edges j will be in a horizontal and the other in a vertical position, thus forming cutting and shear edges of the share, while the lowermost wing or face 'i will properly turn the earth as the plow progresses. The mold-board can thus be shifted to right or left of the shoe and still be in working condition. ()ther well-known forms of double shares or mold-boards might be employed;

but I prefer that described. The share has a shoulder, K, on its under surface near its front end and in line with the apex of point I, and this shoulder fits over the front end of the shoeA and landside and is pivoted to the front end of the shoe by a horizontal bolt, 7;. The rear portion of the mold-board is supported by a shifting quadrant, L, which consists of a bell-crank braee,'l, pivoted at its angle by a bolt, m, in a transverse slot, M, through the shoe, so that the arms of the brace are on opposite sides of the shoe. To the ends of the brace-arms are secured the ends of an arc-shaped rod, N, which passes through a series of eyes, a I), attached to a cross-brace, O, on the underside of the mold-board. The rod N is longer than the width of mold-board I, so that the latter has a certain amount of lateral play thereon but a ny pressure exerted on the face of the mold-lxmird is instantly transmitted to the pivot of the (piadrant L on the shoe A.

Brace O has a central eye, 0, to which is pivotally attached the end of a link, P, the other end of which. is similarly attached to an eye, secured to the plow-beam near the upper end of slot E. \Vhen the mold-board is down, the link P stands at right angles, or nearly so, with the share and beam; but when the beam is retracted the link is drawn back ward. The mold boardbeingpivotallymounted on the shoe, as described, the retraction of t he beam through link P turns the mold-board on its pivots and brings it up centrally over the shoe.

It will be observed that the wings of the mold-board extend rearward beyond the bend of the beam, so that in order to shiftthemoldboard over the shoe it is necessary to get the beam out of the way. This is effected by the lever g and connections, as described. The

by momentum pass the center of gravity and incline toward the opposite side of the shoe, and the operator by then giving the lover a forward thrust pushes back the beam to its proper position on the shoe, and SllIll'lllQtllO- ously through link l forces the mold-board downward on the side of the shoe opposite its position before the beam was retracted.

The mold-board in moving to its new position oseillates the quadrant and causes it to drop toward the mold-board, so that it follows and braces the mold-board .in either of its positions. The vertical edge of point .l will always be in proper line with the side of the landside, and the arm of brace I will be upright and out of the way on the -landside.-

Q q are the similar opposite handles, con

verging at their lower ends and united by a loop, R, which is journaled on a spindle or bolt, '7', in the heel of the shoe, as shown, so that the handles may be shifted laterally. The handles are connected near their lower ends by a segmental plate, S, wh ieh has notch es .s .9 near its opposite ends.

T is a plate having ears 6 '1, embracing the arms C U and suspended from shaft G, and also having a front curved portion, ll, thatembraees segment S and holds the handles in proper uprightposition. 'lhecurved portion U is vertically perforated at a for the passage of the tooth r of a dog, V, mounted on shaft G and connected with lever g, so as to be operatcd thereby. llandle Q is on the right and handle q on the left, and when the plow-beam has been retracted and the mold-board thrown toward the right side of the shoe, as described, the handles can be shifted on their pivot to bring handle (1 inline with the left-hand side of the landside or shoe. This brings the left notch s of segment S beneath the curved portion ll of plate T, and when lever g is thrown forward, as described, dog Vis thrown upward, its tooth r passing through the opening in part U, and also through the left recess .5- of segment S, whereby the handles are locked to plate T and lateral motion thereof is prevented.

'hen the mold-board is shifted to left of the shoe, the handles which are released by the movement of lever g necessary to shift the beam backward) can be shifted to bring handle Q in alignment with the right-hand side of the landside. The arm f and dog V being rigidly conn eeted with lever g, the parts are operated synchronously, as is evident.

The draft on beam 1), after it is retracted, will materially assist the plowman in working the parts, and the lever 9 could be made so long that but little power is required to operate it. The lever stands directly in front of and between the handles and moves in a vertical plane.
